Between the realms isolated by boundary gaps and storms, spiritual contract masters maintain balance with the power of contracts. When the taboo "Contract Splitting Technique" tears apart the peace, Ling Che, a young boy from the Central Realm, an orphan who is regarded as a "contract-breaker", accidentally concludes a contract with the mysterious world gap creature "Zero", awakening the lost ancient contract text.
He will team up with geniuses from the Spiritual Planting Realm and defectors from the Shadow Realm, guard the beast souls under the iron hoof of the machine, and trace the truth in the ruins of the Lightfall. When the ambition of the World Breaking Alliance shakes the foundation of all realms, Ling Che will finally understand: the true spiritual contract is never slavery, but understanding and symbiosis across realms. Using the ancient deed as the key, he will let the stars in every realm shine freely again.
